Hey guys, I posted this on Iatn but I looked at the Usb Autoscope and it is a 8 channel unit with software functionality to find ignition, compression, fuel and timing problems.  Hilarious thing is I think I understand how they are doing it.  They hook up to the crank sensor, hmmmm, they hook up to a ignition synch,hmmmm, then they rev the engine off idle of course to advance the timing and then they rev it again to 3000 rpm and shut the engine off.  Sounds like a hybrid version of Mcct and Spence's Lead ignition timing. :) Anyway go to the site

Hopefully soon they will come out with a Pico 8 channel Auto Scope.  I asked the Pico guy at Vision and he told me it was in the works, but they don't know when yet.  That's what I was told. :)
